I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. Target Secondary monitor when run the application

    Usually developers have more than one monitor, It will be nice if we can target a monitor by default.

      • Add CanTellLength and CanSeekBackwards to System.IO.Stream

        • Add CanTellLength property to the System.IO.Stream:

        public virtual bool CanTellLength {
        get {
        try {
        var length = this.Length;
        return true;
        } catch {
        return false;
        }
        }
        }

        • Add CanSeekBackwards property to the System.IO.Stream:

        public virtual bool CanSeekBackwards => CanSeek;

        • Why
        Working with System.Net.Http.StreamContent I found that it caches the request in memory before sending the HTTP request if the length of the stream is unknown. And to perform the check if the length is known it uses CanSeek property - it mixes completely different concepts.
        I came up with conclusion:
        - The stream can tell…

        • Expose Collation Info of SQL Server Result Set via SqlDataReader

          The exact collation of each string field should be publicly available. The properties can be added to the DataTable returned by the GetSchemaTable() method, or they can be added as individual properties and/or methods of the SqlDataReader class, or a combination of both. The properties are:
          1) LCID
          2) SqlCompareOptions
          3) collation_name (e.g. Latin1_General_100_BIN2)

          The "LCID" and "SqlCompareOptions" values already exist in the "SqlDataReader" class, but are private or internal ( http://referencesource.microsoft.com/#System.Data/System/Data/SqlClient/SqlDataReader.cs,277 ). These would make sense to put into the GetSchemaTable output.

          The "collation_name" value is necessary due to the combination of "LCID" and "SqlCompareOptions" not being enough to…

          • XmlSerializer should recognize "True" as a valid boolean (Case insensitivity)

            Problem: "true" is recognized as valid by XmlSerializer, while "True" with a capital T is not.

            Expected behavior: Clearly, the value is unambiguous and valid and should be recognized as the boolean value "true".

            Error trace:

            • make another foreach can be set and can use foeach similar to LINQ

              now foreach is readonly,

              I suggest ther can be a new foreach that can be set and have a different name like foreachset

              and originally I have to write in an independent line as:

              int[] iArray = new[] {1, 2, 3};
              foreachset (int i in iArray)
              {
              i += 3;
              }

              .

              and I hope it can be written like:

              int[] iArray = new[] {1, 2, 3};
              iArray.foreachset( i => i+=3);

              its more Intuition.

              or even just readonly foreach like LINQ is good,

              I can do some readonly action such as

              iArray.foreach( i => Console.Writeline(i));

              -----------

              Select in LINQ seems…

                  • Dynamic class

                    Include support for dynamic class in .net.

                    This should allow the developer to take existing classes and either add more properties to the class in a new class, or remove properties.

                    This will allow the developer to create DTO classes from original classes, cutting away the properties he wants, but maintaining the ones he wants as well.

                    • Add an Attribute to specify an XML-schema for verifying and validating web API (WebApi) calls.

                      Today there's the possibility of crating a class that can be used to define an input parameter for a web-API. You are able check weather the web-API framework manage to parse the input XML and map it to your input parameter (class).

                      This is not the same as validating the submitted XML against an xml-schema, the way you can do if you manually load the XML by adding a schema to the xmlReaderSettings.

                      A new attribute should be introduced, where it is possible to specify the schema for the web-API.
                      It should also be possible to specify a delegate for…

                        • Add .ToTitleCase() to String Class

                          Add the method .ToTitleCase() to the String Class (or a similar one, such as .ToProperCase() or somesuch). Currently this requires pulling thread information to get the local user's culture information, and multiple extra lines of code. It would be much simpler to have an easily accessible method to capitalize the first letter of each word in a string.

                          Current implementation:

                          internal static string DisplayRandChar()
                          {
                          Character randomCharacter = new Character();

                          CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;

                          TextInfo textConvert = cultureInfo.TextInfo;

                          string displayText = ($"You are {textConvert.ToTitleCase(randomCharacter.name)} the " +
                          $"{textConvert.ToTitleCase(randomCharacter.item)}-wielding {textConvert.ToTitleCase(randomCharacter.occupation)}!");

                          return displayText;
                          }

                          Simplified implementation:

                          internal static string DisplayRandChar()
                          {
                          Character…

                              • Allow code within a compiled project to enumerate the conditional symbols used to build it

                                While conditional symbols can alter the code generated there is no way for a compiled program to enumerate the symbols used to compile it.

                                If this were possible then programs could log this information or notify administrators as to how the code was built, providing verification that the correct symbols were used for a given use case.

                                Manual mechanisms could be build around the compilers, but those mechanisms might themselves become points of failure.

                                      Business enterprise uses middleware (SOA Architecture) to build their applications to be scalable. Why not allow add WCF reference to ASP.NET Core?

                                      • Release .NET Framework 4.6 full installer to Windows Server Update Services

                                        Currently you have released all versions of .NET Framework 4.x full install to WSUS with the exception 4.6 and as an enterprise that uses WSUS we would like to have an update that we can deploy that will install 4.6 into applicable environments that don't have it.

                                        • An effective way to compress Large Object Heap

                                          I think I've found an effective way to compress LOH:
                                          If CLR always alloc every large object at the beginning of a RAM page(usually 4KB per page),then the large object heap(LOH) can be compressed without much cost: CLR can compress LOH by modifying page table and TLB instead of copying data. If so, small fragmentation maybe still exist (less then a memory page size per fragment), but there would be no large fragmentation, and compressing would be very fast because of not copying large amount of memory data. To do this, OS support may be needed, fortunately Windows OS and…
